It must be some stuff. Dosed at 100000:1 and its cutting through the dirt? I keep waiting for someone to shout 'April fool' but it's not April
i do think it cuts through dirt easier than just pure.on snail trails its really noticable.
its the shine thats really great though.i do think the frames and sills on white UPVC look dull after a while using pure but with vision treated water it adds a really nice shine.
for the price of it(i estimate itll cost me around 40p a day)its worth it IMO for the extra shine alone.
Dazmond what causes window frames to dull over time, its not cleaning with pure water its the effect of the sun on the UPVC.
To keep it short what actually happens is the surface goes from being smooth to getting little burrs or hairs at a
microscopic level.
To keep it simple the only way to bring the shine back onto the frames is to cover them in a glossy compound or polish the
burrs off.
So this product either covers the frame in a glossy compound or melts the burrs on the UPVC which I don't think would be
good for the frames over time, but to be honest I don't think it does either.
Its the same with car paintwork so there's no way it could have made your van shinier.
So you can understand why people who know a little bit about how thing work would think its an April fool.
